I'm looking for an engine splash shield for my 2003 bmw 540i M. Dealers are the only ones that seem to be able to get the part in but at $238.00 plus labour is crazy. I have posted in the "looking for section" but looking directly for help from you guys. Any help would be much appreciated in helping me find this part.

Joe, you got your self a deal! Trust me shipping something of this size will cost you more than the part itself...don't foget customs and handling fees. Also, it's broken beyond repair (in my opinion). I'd be VERY happy to find a used one but they are hard to find.

So I looked at this last night.. the center plastic undertray is not broken, only the piece with the air temp sensor on the passenger side. I was able to reattach it a little more firmly. I believe this is the part number: 51712498990. I found it on here:

One problem is though that the center undertray mount points / tabs are bent. So on the drivers side, it lines up with the left tray, but it gently slopes up until it is flush with the bumper cover on the right side. The right (broken) tray sits a full 1.5" lower than the center section. Anyone know what the mounting points for the center piece are like? I imagine you could just remove the center piece and bent the mounting points back, but maybe its not that simple.

However, that wasn't the source of the noise. There is a large rattle coming from the rear passenger side of the car. I found a piece of plastic rubbing and loose, braced it with card board but it didn't help. Any ideas?

Yeah the mount points would be super easy to fix, they're just tabs, then those annoying metal backing clips go on there, and the screw for the panel then just goes through and locks. If that piece is broken it's also pretty cheap, even from the dealer. I destroyed mine when I ran over my blue box, and had it replaced in 30min. i think it was $50 from the dealer, providing it's similar price to the M-bumper one.

For the rattle, could it be a broken shock mount in the rear? They've been known to go.

Unfortunately even to look at them, the rear seat and full rear parcel shelf needs to come out, plus the speaker pods.. It's somewhat of a PITA. You can pretty much fully replace the front struts in a quarter the time it takes to even get the rear shocks out.
